Through 26 model-building exercises, you’ll investigate all six classic simple machines (wheels and axles, levers, pulleys, inclined planes, screws, and wedges) plus gears. Things start simply, then get more complex as you work through the 32 page manual.
The models can be assembled and disassembled again and again, letting you experiment and create models of your own!
